<p>The present invention relates to a vacuum interrupter in a vacuum circuit breaker. According to the present invention, there is provided an attraction member(180) made of a ferromagnetic body for surrounding between the stationary electrode(130) and movable electrode(140) to attract a radial magnetic field generated in a radial direction between the stationary electrode(130) and movable electrode(140) by means of the attraction member(180), and through this a component of the radial magnetic field may be increased in an overall horizontal direction between the stationary electrode(130) and movable electrode(140), and as a result the radial magnetic field may be further enhanced between both electrodes, thereby strengthening an arc driving force.</p> |
